Elasticsearch splits the data by shards, and the shards are written to the data path with the most free space. If one shard receives most of the writes then your performance is limited to the speed of one data path. If however, your data is being written evenly across data paths then you will get the write speed of all the disks being used.
One answer is that there are two types of data you might want to store in Elasticsearch: Your JSON documents, containing numbers, lists, text, geo coordinates, and all the other formats Elasticsearch supports. Let’s look at both of these in detail.
Where is the Elasticsearch data stored?
According to the documentation the data is stored in a folder called “data” in the elastic search root directory. Show activity on this post. If you run the Windows MSI installer (at least for 5.5.x), the default location for data files is: The config and logs directories are siblings of data. Show activity on this post.
As others have pointed out, path. Data will be where Elasticsearch stores its data (in your case indexed logs) and path. Logs is where Elasticsearch stores its own logs. If you can’t find elasticsearch. Yml, you can have a look at the command line, where you’ll find something like -Des., and path., and conf=/opt/elasticsearch/config.
If you’ve installed ES on Linux, the default data folder is in /var/lib/elasticsearch (Cent. OS) or /var/lib/elasticsearch/data ( Ubuntu) If you’re on Windows or if you’ve simply extracted ES from the ZIP/TGZ file, then you should have a data sub-folder in the extraction folder. On Windows 10 with Elastic. Search 7 it shows:.
So the default path to logs is /var/log/elasticsearch/elasticsearch. Log Show activity on this post. As others have pointed out, path. Data will be where Elasticsearch stores its data (in your case indexed logs) and path. Logs is where Elasticsearch stores its own logs.
How do I monitor my Elasticsearch cluster?
You can use Elasticsearch’s application logs to monitor your cluster and diagnose issues. If you run Elasticsearch as a service, the default location of the logs varies based on your platform and installation method: On Docker, log messages go to the console and are handled by the configured Docker logging driver.
How do I view Elasticsearch logs in Docker?
On Docker, log messages go to the console and are handled by the configured Docker logging driver. To access logs, run docker logs. For Debian installations, Elasticsearch writes logs to /var/log/elasticsearch. For RPM installations, Elasticsearch writes logs to /var/log/elasticsearch.
Why is Elasticsearch performance limited to the speed of one disk?
If one shard receives most of the writes then your performance is limited to the speed of one data path. If however, your data is being written evenly across data paths then you will get the write speed of all the disks being used. Elasticsearch does not ensure writes are spanning many data paths thus performance is variable and not consistent.
